Quin, Pezzillo
was in 1834, practicing Homoeopathy in Naples. Dadea says that he was one of the active
managers of the Effemeridi, an early homoeopathic journal, and that he was
esteemed.

But that he was affected by the unfortunate disposition to conciliate
in matters that are irreconcilable, and he styled himself an eclectic ;
and to promote eclecticism in medicine and to reconcile discordant
opinions on the principles "similia similibus" and " contrariis contraria " he read and publicly defended two essays before
the Naples Academy of Medicine.

In the Effemeridihe stoutly contended for these views and the
discussion would not have been inglorious for him had not the cause of
conciliation and eclecticism been desperate. (World's Conv., vol. 2, p. 1086.
